Summary
This proposal seeks to update the USDCx interest rate parameters to better position the Liqwid USDCx market within the broader Cardano lending ecosystem and accelerate borrow demand discovery.
Unlike the gradual and methodical adjustment framework established through LIP-145: Establish Parameter Committee for Interest Rate Management, this proposal introduces a more significant one-time adjustment intended to rapidly test market responsiveness and improve capital efficiency.
This proposal also complements LIP-123: Disable Loan Origination Fee for USDCx Market, which pursued the same broader objective through the removal of the loan origination fee: increasing borrowing activity and improving utilization in the USDCx market.
Motivation
As outlined in LIP-123, the USDCx market on Liqwid Finance has consistently exhibited utilization rates below optimal levels, indicating underutilized liquidity and reduced capital efficiency.
One likely contributing factor is the current interest rate curve, which - despite being lower than some other stablecoin markets on Liqwid - remains materially less competitive than alternative borrowing venues across the Cardano ecosystem.
As a result, borrowers may be incentivized to source liquidity elsewhere where borrowing costs are lower and more predictable.
This proposal aims to address that imbalance by significantly reducing borrowing costs while preserving protections against excessive utilization and liquidity stress.
Specification
This proposal recommends:
- Significantly reducing the USDCx interest rate curve
- Maintaining the existing 90% optimal utilization ratio
- Preserving a relatively high maximum interest rate at full utilization to discourage market overheating and protect liquidity availability during periods of elevated demand
| Parameter | Current | Proposed |
|---|---|---|
| Base rate | 5% | 5% (unchanged) |
| Optimal utilization ratio | 90% | 90% (unchanged) |
| Optimal rate | 25.76% | 8% |
| Max rate | 47.39% | 40% |
Expected Impact
- Higher borrowing demand: Lower borrowing costs may attract both new and existing borrowers
- Improved utilization: Increased borrowing activity should improve capital deployment efficiency within the USDCx pool
- Greater protocol activity: Higher utilization and borrow volume should increase aggregate interest generation over time despite lower rates
- Competitive positioning: Aligns Liqwid more closely with prevailing borrowing conditions across the Cardano ecosystem
- Faster market feedback: A larger adjustment enables clearer observation of borrower demand elasticity and market behavior
Risks & Considerations
- Behavioral uncertainty: Borrow demand may not respond proportionally to lower rates
- Revenue trade-offs: Lower rates could reduce short-term lender yield and protocol revenue if utilization does not sufficiently increase, however, given the currently low utilization of the USDCx market, the downside risk is comparatively limited relative to similar adjustments in larger or more heavily utilized markets
- Market-specific scope: This proposal targets only USDCx; further adjustments to other markets may be considered based on outcomes
Forward-Looking Considerations
This proposal may serve as a useful pilot for future interest rate optimization across Liqwid markets.
Depending on the observed effects on utilization, borrow demand, lender behavior, and protocol revenue, future governance discussions may evaluate similar adjustments for other stablecoin markets such as DJED, wanUSDC, and wanUSDT.
Additionally, the accelerated feedback generated by a larger one-time adjustment may provide valuable empirical data to support future parameter committee decisions under the framework established by LIP-145.
Next Steps
- Vote on the proposal
- Implement the updated USDCx interest rate parameters
- Monitor post-implementation metrics, including:
- Utilization rate
- Borrow volume
- Supplier APY
- Protocol revenue
- Liquidity stability
